| 英文摘要 | Low temperature co-fired ceramics composite is fabricated by mixing B2O3–La2O3–MgO–TiO2(BLMT) glass matrix with BaTi4O9ceramic filler and the influence of the filler on sintering behavior, phase composition, microstructure and dielectric properties of the composite is investigated. The results show that the densification of composites can be achieved at 860 °C for 20 min by three-stage reactive liquid assisted sintering process, consisting of glass redistribution and local grains rearrangement, viscous flow, and solid state sintering and closure of pores. The XRD patterns exhibit that the main phase of all samples is LaBO3phase formed from the crystallization of BLMT glass and the secondary phases have changed due to chemical reaction between BLMT glass and BaTi4O9forming two new phases BaTi(BO3)2and TiO2during sintering. Meanwhile, the microstructure results indicate that the reaction helps to eliminate the closed pores in composites. As the filler is increased, the dielectric constant and quality factor firstly increases and then decreases, while the temperature coefficient of resonant frequency increases. Typically, the 30 wt% BaTi4O9-filled BLMT glass composite sintered at 860 °C for 20 min displays dielectric properties of ΕΕr= 20.49, Q × f = 24000 GHz and ττf= +145 ppm/°C. © 2017, Springer Science+Business Media, LLC. |
